Demographic data like gestational age at birth, postnatal life time, total age at death (Gestational age + Postnatal life time) and gender are represented in separate columns. The cause of death, postmortem time (from death to the autopsy) as well as clinical signs and neuropathological aspects, showing the most relevat aspects of the autopsy report, are described. Abbreviations: h: hours, d: days, w: weeks, F: female, M: male.
